Troubleshooting for excessive air bubbles in project

     There are many types and causes of excessive air bubbles                         We have listed a few below:

           -   Across the Entire Surface   -

1) No bubble removal technique was used as shown in our instructions (ex.heat gun or plumber’s torch).

2) Improperly applied or no seal coat was used.

3) The wood surface below was extremely porous, and the seal coat was not thick enough to cover. (Very common in aged wood)

4) The product was whipped or stirred excessively. Be sure not mix epoxy too quickly or too rigorously, and this will incorporate additional air bubbles into the mixture before you pour.

(Tip - If you use a drill with a stirring paddle, be sure to use its lowest range to avoid making excessive bubbles)

                 -   Just in One Spot 

1) Knots, cracks, or holes in wood were not properly sealed, and air bubbles continually rose throughout the curing process.

2) Missed a spot in the seal coat.

                          - Solution - 

Usually, the bubbles are not noticeable enough to warrant any further work. If, however, you desire, you may sand or grind the surface to remove as much of the air bubbles as possible and re-coat the entire surface. Spot-fixing results in a raised (speed bump) looking area and is much worse looking than the bubbles themselves.


TIP- Keep in mind while you're mixing, the mix will go from cloudy to a clearer consistency, but you will still see small bubbles in the mix. This is fine! Go ahead and pour on your tabletop and you will be able to get rid of the bubbles with a heat gun after you pour.
